Features of Reversi Web
A free Reversi (Othello) game that you can play instantly on the web. Supports AI matches, online matches, and digital Reversi board.
This site was developed because the creator, a student at Keio University SFC, experienced a lack of online Reversi games on the web. Since then, I have added many features, including unique online match matching and various AI levels. I will continue to improve our services, so please stay tuned.
About Local Reversi Board Mode
In Local Reversi Board mode, you can play Reversi on a single device. It is convenient for playing Reversi with family or friends on-site, or for carefully considering strategies.
Below the board, the number of stones on the board and (if enabled in Settings) the game evaluation are displayed.
Play in App Mode
Although this site is a browser game, you can also add it to your home screen as a web app. It takes only a few seconds and consumes almost no device storage. On the other hand, the game launches even faster and you can use the main features offline. Please give it a try!
About Reversi (Othello)
Basic Rules
Reversi is a board game where you capture your opponent's pieces by surrounding them. It is also known as 'Othello'. The game proceeds according to the following rules.
- Black goes first, followed by White, taking turns placing stones.
- When you surround your opponent's stones, they are flipped to your color. You can surround stones in any direction: vertically, horizontally, or diagonally.
- You can only place your stones on squares where you can surround your opponent's stones ( valid moves ).
- If you have no valid moves, the system will automatically pass your turn to your opponent. The game ends when both players pass.
Highlighting Valid Moves
Reversi Web has a feature that automatically detects and displays valid moves. This feature can be turned off in Settings.
Time Limit
You can set a time limit to increase the game's pace. The shortest option is the 10-second rule, allowing for ultra-fast matches!
Winning Conditions
- At the end of the game, the player with the most pieces wins.
- In matches with a time limit, you also win if your opponent runs out of time.
- In online match mode, the forfeit button is available. If your opponent forfeits, you win.
